SPECIFICATION forming part of Letters Patent No. 333,480, dated December 29,1885. Application filed October 24, 1885. Serial No. 180,859. (N model.)

To all whom, it may concern: of the tenon of the railroad-chair, and give a Be it known that I, LYMAN B. PRINDLE, a greater bearing to the tenons of the chair. citizen of the United States, resident at Ban- The tie will be about from six to seven inches tam, in'the county of Litchfield and State of wide, and the flanges B B will be from one to 55 Connecticut, have invented certain new and one and one-halfinch deep.

useful Improvements in Metallic Railway Ties It has been demonstrated beyond controand Chairs; and I do declare the following to versy, both in this country and in Mexico, be a full, clear, and exact description of the that the rail must rest on wood, and not on invention, such as will enable others skilled metal or stone. Ifit rests on either metal or 60 IO in the art to which it appertains to make and stone, both the rail and the rolling-stock will use the same, reference being had to the acconibe pounded out and worn out by use in a short panying drawings, and to letters or figures of time, as has been demonstrated both in this reference marked thereon, which form a part country and in Europe. I have investigated of this specification. the matter and have satisfied myself that one- 6 5 Figure l of the drawings is a representafourth inch in thickness of hard wood under tion of this invention, and is a vertical section the rail is as good, and will protect the rail as taken across the rails. Fig. 2is a detail and well as one foot in thickness will do. The a vertical section. Fig. 3 is a perspective chair holds the wood in place, and when the view of the chair.
